The email headerregistry class MessageIDHeader is too strict when parsing existing Message-Ids. It can truncate Message-Ids that are valid according to the obsolete rules. As the saying has it: "Be liberal in what you accept, and conservative in what you send." I think the parser should be much closer to the UnstructuredHeader.
